摘要
运用空间分析方法探索中原城市群经济变化趋势、分布结构与形成原因。整体看,2005—2015年中原城市群经济空间差异呈缩小趋势,特别是中部偏西地区、东部及南部地区,表现出与周边地区协同发展态势。人均GDP由南向北呈现先增加后减少的趋势。局部空间自相关分析显示:扩散效应区(HH区)主要位于中部偏西地区,低速增长区(LL区)主要位于东部及南部地区。冷热点城市分布格局与之一致,温点城市呈现由东北—西南格局向南—北格局再向北部地区集中的转变态势。克里金插值发现,中原城市群经济发展受中心城市的影响和辐射逐渐增大,经济空间差异的缩小并非区域协调发展所致,而是空间分异的表现。初始区域政策、交通因素和经济活动的扩散效应是中原城市群核心带动、深化开拓和整体发展3个阶段经济空间差异的主要原因。
Spatial analysis method is used to explore spatial variation trend, distribution structure and formation cause about economic in Zhongyuan Uurban Agglomeration. Economic spatial disparities of Zhongyuan Urban Agglomeration shows a trend of narrowing during 2005—2015, especially, central west region and eastern and southern regions shows the coordinated development with the surrounding areas. Per capita GDP shows an overall trend of increasing first and then decreasing from south to north. The results of local spatial autocorrelation analysis show that the HH districts （diffusion effect districts） distribute in central west region, the LL districts （low-speed growth districts） distribute in eastern and southern regions, which is similar to distribution pattern of cold cities and hot cities, warm cities show the changing trend of northeast southwest pattern to south north pattern to focus on northern region. Through Kriging interpolation, it is found that the influence of central city on the economic development in Zhongyuan Urban Agglomeration is increasing gradually. The narrowing of economic spatial difference in Zhongyuan Urban Agglomeration is not the result of regional coordinated development, but the manifestation of spatial disparities. Initial regional policy, traffic factors and the diffusion effect of economic activities are the main reason for the spatial disparities of the three stages of core drive, deepening development and overall development in Zhongyuan Urban Agglomeration.
